Abstract
A method and system including: transmitting, by an access point (AP), a multi-user request to send (MU-RTS) frame requesting a non-AP station (non-AP STA) to respond with a clear to send (CTS) frame on one or more 20 MHz non-primary subchannels; and receiving, by the AP, a CTS frame from the non-AP STA on the one or more 20 MHz non-primary subchannels.
Claims20
A method comprising:
- transmitting, by an access point (AP), a multi-user request to send (MU-RTS) frame requesting a non-AP station (non-AP STA) to respond with a clear to send (CTS) frame on one or more 20 MHz non-primary subchannels;
- and
- receiving, by the AP, a CTS frame from the non-AP STA on the one or more 20 MHz non-primary subchannels.
A method comprising:
- receiving, by a non-access point station (non-AP STA) from an access point (AP), an multi-user request to send (MU-RTS) indicating that the non-AP STA responds with a clear to send (CTS) frame on one or more 20 MHz non-primary subchannels;
- performing, by the non-AP STA, a carrier sense operation on the one or more 20 MHz non-primary subchannels to determine whether the 20 MHz non-primary subchannel is idle;
- and
- transmitting, by the non-AP STA, a CTS frame on the one or more 20 MHz non-primary subchannels when the corresponding 20 MHz non-primary subchannel is idle based on the carrier sense operation.

An wireless system, comprising:
- non-access point station (non-AP STA);
- and
- an access point (AP), comprising a processor configured to:
- transmit a multi-user request to send (MU-RTS) frame requesting a non-AP station (non-AP STA) to respond with a clear to send (CTS) frame on one or more 20 MHz non-primary subchannels;
- and
- receive a CTS frame from the non-AP STA on the one or more 20 MHz non-primary subchannels.
